AUTOMATIC MEASURE FOR WO OLD SAW TABLES.

Application filed June 13, 1925. Serial No. 36,779.

vented certain new and useful Improve.

provision of a measuring device for saw tables by means of which logs, or the like may be rapidly measured for being cut into uniform lengths. V

a A further object of the invention is to provide a measure of the above mentioned type which is adjustable for permitting logs to be cut into sections of any desired, uniform length.

A still further object of the invention is to arranged when the log carriage is in a position to start a'cut, so that a log may be measured at that time, but will be rendered inoperative after the out has been made, so that the part severed from the log may be be removed without interference from the measuring elements.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front elevational view of the device embodying this invention,

Figure 8 is a vertical sectional view taken upon line VIIIVIII of Fig. 7.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numerals 5 designate the legs of the support or table which further includes the front and rear skirts 6 and 7 respectively and the end skirts 8 and 9.

Mounted upon the front and rear skirts' 6 and 7 are the parallel cross bars 10 which are arranged at one end of the saw table.

Mounted upon these cross bars 10 is a platform 11 having an upstanding rear wall 12. Joined to the cross bars 10 and this rear wall 12 are a pair of shaft bearings 13 in which is rotatably mounted the shaft 14 having the circular saw 15 carried by one end and the pulley 16 carried by the remaining end, the said saw and pulley being ar ranged at opposite ends and located beyond said ends of the platform 11.

Supported by the front and rear skirts 6 and 7 are the parallel tracks 17 which project forwardly of the front skirt 6, as best illustrated in Figs. 4 and 5. Mounted upon these tracks 17, by means of the grooved wheels 18 carried by the shaft 19 journaled in the bearings 20, is a log carriage 21 which has an upstanding wall 22 at its rear longitudinal edge. Depending from this carriage 21 are the movement limiting arms 23 which are intended to engage. the pin 24 carried by one track 17 and should this pin 24 be removed, to engage the pin 25 carried by the remaining track 17, for limiting the rearward movement of the carriage 21. The forward movement of the carriage is limited by these arms 23 engaging the inner face of the front skirt 6.

The automatic measuring device embodying this invention includes a guide plate 26 which is centrally apertured at .27 and is mounted upon the platform 11 for adjustment longitudinally thereof. To permit this adjustment of the guide plates 26, the platform 11 is provided with a plurality of elongaged slots 28 into which binding bolts 29 project. The platform 11 is further provided with an elongated slot 30 which registers with the aperture 27 formed in the plate. In Fig. 6 there is shown an angular lever 31 formed with a transversely extend ing aperture 32 intermediate its ends and has a stop member 33 connected by the hinge 34 to one end. This aperture 32 receives a fulcrum bolt 35 which is adjustably received within an elongated slot 36 formed in the front skirt 6 of the support or table. The remaining end of the lever 31 is provided with an aperture 37 best illustrated in Fig. 6, through which the bolt 38 projects and by means of which any desired number of.

vided with an eye screw 40 to which is attached a flexible cable 41 that extends upwardly to travel over a grooved pulley 42 carried by the bracket 43 and from this pulley to a depending arm 44 adjustably secured to the rear wall 22 of the log carriage 21 by the bolt 45 and vertically extending elongated slot 46. This cable guiding pulley 42 has its supporting bracket 43 extending through the slot 47 formed in the strip 48 carried by the front skirt 6 for permitting the said bracket to be adjusted longitudinally of the said skirt. To maintain this supporting bracket 43 in its desired adjusted position, a bolt 47 is connected to the bracket and may be received in any of the apertures 48 formed in the front skirt 6.

It will now be seen that the adjustability of the guide plate 26, the lever 31, and the cable guide pulley supporting bracket 43, will permit the stop 33 to be adjusted longitudinally in respect to the carriage 21.

The operation of this device may be described as follows It will be understood that the pulley 16, carried by the saw shaft 14 is to be connected to a suitable source of power by means of which the saw 15 may be driven. The various elements employed for operatively connecting the stop 33 with the carriage 21 should be adjusted for arranging the said stop to provide the desired space between the plane of the saw 15 and the stop so that the log L placed upon the carriage 21 may be moved until one end engages the stop whereby the proper length cut will be made. By moving the carriage 21 rearwardly along the tracks 17, the log L will be acted upon by the saw 15 for severing therefrom the portion of the log arranged between the plane of the saw and the stop 33. This rearward movement of the carriage 21 will cause the lever 31 to be pivoted, due to the connection between the carriage and the weighted end of the lever, for moving the stop 33 into an abnormal position below the top plane of the platform 11. By the time the section is served from the log L, the carriage 21 has been moved to its limit of rearward movement on the tracks 17 and the stop 33 has been arranged for permitting the severed portion of the log to be rolled off of the platform 11 without interferring therewith. Upon returning the carriage 21 to the position illustrated in Figs. 1, 2 and 4, the tension upon the cable 41 will be re-' moved and the weights 39 will pivot the lever 31 for returning the stop 33 to its operative position, as illustrated in Figs. 1, 2 and 3. The log L may then be moved longitudinally of the carriage 21 for placing one end of the same in engagement with the stop 33, whereupon the carriage may again be moved for causing the saw 15 to out another section from the log.

It is to be understood that the form of this invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-' joined claim.

Having thus described the invention, I claim In a device of the type described, a support, a power saw carried thereby, a carriage movable on the support for properly feeding a log against the saw to cause a section to be severed from the log, an apertured guide plate carried by the support longitudinally of the carriage and adjustable in respect to the latter, a lever pivoted on a fulcrum pin carried by the support and adjustable longitudinally of the carriz'ige, :1 stop hinged to one end of the lever and projecting into the aperture of the guide plate, a weight on the lever for normally holding the stop projected above the top plane of the support, and a connection between the remaining end of the leverand the carriage for causing the lever to pivot to move the stop below the top plane of the support when the carriage is moved to make the out.

In testimony whereof I affix my signature.

CHARLES H. FREDENBURG.
